SPECIFICATION forming part of Letters Patent N 0. 720,566, datedFebruary 17, 1903.

Application filed April 12, 1902.

T0 aZZ whom it may concern:

Be it known that I, ANDREW OOULTER, manager of spinning factory, asubject of His Maj esty the King of Great Britain, residing at IRegherstrasse 7, Mitau, Kurland, in the Empire of Russia, have inventednew and useful Improvements in Belt-Shipping Devices, of which thefollowing is a clear and exact specification.

My invention relates to a belt-shipping device of the constructionwherein the belt is operated upon bya bevel or oblique-ended barprovided with curved arms and arranged ro tatably on the pulley-shaft.

The object of this invention is to facilitate and to assure the actionof the shipping-bar, and consequently the operation of the belt, andparticularly to perfect the belteshipper so that the latter is not anobstacle in the way of unshipping the belt or of adjusting or shippingit again. For this purpose the belt-shipper carries a slide-rod movablein guides on the bearing, the rod being provided with two pivots forreceiving a specially-formed operating-bar. The latter has no fork, butis provided with a resilient hook, the opening of which is placedlaterally, so as to engage with one or the other of the pivots. Thelower pivot of the slide-rod is provided with a resilientpawl. Thisconstruction of the beltshipper and its operating-rod allows the shipperto maintain such a position while the-belt is on the pulley and duringits unshippi'ng that it cannot cause any disturbance, while at the sametime its handling during the shipping of the belt is easy and safe.

In the drawings, Figure 1 is a side View of the pulley with the shipperin its initial position. Fig. 2 shows the same parts in a preparatoryposition of the shipper. Fig. 3 shows the same parts as-in position atthe beginning of the shipping operation. Fig. 4 shows the parts as theyappear immediately after the shipping operation has been completed. Fig.5 is an end view'of the pulley and of the shipping device, showing theparts in a position when the slide-rod is brought back to the initialposition shown in Fig. 1. Figs. 6 and 7 show a side and an end View ofthe operating hooked rod on an enlarged scale, and Figs. 8 and 9 show anend view and a side View of the lower part of the slide-rod with theresili- Serial No. 102,606. (No man.

ent pawl'in natural size. Fig. 10 is a side View of the pulley andbelt-shipper after a partial completion of the operation of shipping thebelt.

The shipper a, consisting of a beveled bar of known construction, (seeFig. 5,) turns loosely with its bearing 1) around the shaft 0, itslateral position being secured by an adjustingring (not shown) fixedwithin the bearing on the shaft. The bar a carries the parts d, e, andf,which prevent the belt from slipping during the shipping operation. Thebearing his provided according to the present invention with a guideg,in which is movably fitted a sliding rod h, carrying at its upper andlower ends studs or pivots 'i and j, provided with enlarged heads. Thelower pivot j is not arranged rigidly upon the bar 71, but on acatch-lever Z, Figs. 8 and 9, pivotally arranged on the bar h andengaging with a spring-pawl is. On pushing the bar it upwardly, Fig. 2,the pawl is springs over the lower part 19 of the guide g, and thusprevents the slide-bar from descending. The disengagement of thislocking device is automatically effected by means of the hooked rod 1%when the slide-rod h is drawn in the direction of the arrow, as shown inFig. 5, since the catch-lever Z tends to turn about its pivot and itscatch presses the pawl against the action of its spring, thus releasingthe pawl and allowing the rod h to slide through the slot of the guidepart 19. The hooked rod m, Figs. 6 and 7, carries a hook it, the openingof which corresponds with the diameter of the pivots t' and j and isarranged laterally. The hook at is hinged and is under the influence ofa flat spring 0, arranged on the side of the hook opposite to that ofits opening.

The operation of the device is as follows: The belt 8 being unshipped,the shipper is in the position shown in Fig. 1, in which the belt restsupon the circumference ofthe bearing b of the shipper 00.; Then theupper pivot i of the slide-rod his engaged by the hooked rod on andpushed upward, as shown in Fig. 2, until the pawl kis brought inengagement, as aforesaid, and the rod h is prevented from descending.Hereupon the upper pivot 'L' is engaged by the hooked rod m from theopposite side, as shown in Fig. .3, and by pulling the rod m downwardand then pushing it upward the shipper is brought from the position inFig. 3 successively into the positions shown in Fig. and Fig. 4. Byturning the shipper in the said manner the belt 8, which during theoperation is prevented from slipping by the parts cl ef, is shipped bymeans of the beveled end (see Fig. 5) of the bar a onto the pulley, asshown in Fig. 4, while the shipping-bar has the tendency to further turnin the direction of rotation of the pulley and to carry with it thehooked rod m. The operator holding the rod 972 would consequently feel astrong shock in his hands, which shock under certain circumstances wouldthrow the rod out of his hands or injure him. As, however, the frictionin the bearing and the momentum of inertia is utilized for bending thespring 0 of the hook it, a shock or dangerous pull is prevented and thepower exerted upon the hooked rod is yieldingly compensated. In case theslide-rod h should remain in the position shown in Fig. inconveniencescould occur during the unshipping of the belt, as the latter could becaught by the bar, and instead of falling on the bearing 1) it would becaught and damaged. After the release of the upper pivot 2', therefore,the lower pivot j is engaged with the hooked rod on and pulled down, asshown in Fig. 5, so that the pawl 7.; is thrown out of engagement, asabove described, and the slide-rod 7t brought back into its initialposition, as shown in Fig. 1.

What I claim is-- 1. Abelt-shippingdevicecomprisingashipper-bearingloosely mounted on the shaft of a pulley, a rotary bevel-endedshipping-bar fixed radially to said shipper-bearing, a rod slidablymounted on the shipping-bar and provided with two studs on its upper andlower end, respectively, the upper stud being arranged rigidly and thelower being pivotally hinged, a resilient pawl hinged on the slidablerod, and means carried by the hinged stud for engaging the pawl whensaid stud is drawn downwardly, substantially as set forth.

2. Abel's-shippingdevicecomprisingashipper-bearing loosely mounted onthe shaft of a pulley, a rotary bevel-ended shipping-bar fixed radiallyto said shipper-bearing, a rod slidably mounted on the shipping-bar andprovided with two studs on its upper and lower end, respectively, theupper stud being arranged rigidly and the lower being pivotally hinged,a resilient pawl hinged on the slidable rod, and means carried by thehinged stud for engaging the pawl when said stud is drawn downwardly, incombination with a rod having hinged to its end an annular hook with alateral opening, and a spring arranged on the side opposite the openingof the hook to yieldably maintain it in approximate alinement with therod, substantially as set forth.

In witness whereof I have hereunto set my hand, in the presence of twowitnesses, at Riga, March 20, 1902.
